Question

我试图在页面中检测到提交事件后，从JavaScript传递到php文件的JSON数组中创建.csv文件。

我到了可以看到数组从JSON回来的数据......它将它传递给php文件，然后让php文件解析对象并将其输出到.csv文件中

我已经包含了我用来制作它的HTML，JavaScript和PHP ......我能指出正确的方向吗？

我得到的错误因以下因素而异：

当我尝试手动注入我的阵列时：

http://localhost/~admin/dev/parse.php?submittedResults=[[%22uploads/featured/doublewm-3683.jpg%22,%22featured%22]]

当我尝试让JavaScript进行数组传递时：

HTML：

<form onsubmit"">
      <div class="imageTile">

        <input class="data" type="hidden" name="imageFilename" value="uploads/featured/doublewm-4097.jpg">
        <input class="data" type="hidden" name="imageGalleryID" value="featured">
        <label for="uploads/featured/doublewm-4097.jpg">Keep<input class="checkbox" type="checkbox"></label>
    </div>
    <div class="imageTile">

        <input class="data" type="hidden" name="imageFilename" value="uploads/featured/moon-5469.jpg">
        <input class="data" type="hidden" name="imageGalleryID" value="featured">
        <label for="uploads/featured/moon-5469.jpg">Keep<input class="checkbox" type="checkbox"></label>
    </div>
    <div id="submit_buttons">
        <button type="reset">Reset</button>
        <input class="submit" type="submit" onclick="return false" value="Submit">
    </div>
</form>

JAVASCRIPT：

$('.submit').click(function(event) {
    event.preventDefault();
    var imageTile = this.parentElement.parentElement.getElementsByClassName('imageTile');
    var l = imageTile.length;
    var data = [];
    for (var i = 0; i < l; i++) {
        if (imageTile[i].getElementsByClassName('checkbox')[0].checked) {
            var dat = imageTile[i].getElementsByClassName('data');
            console.log(dat);
            var ll = dat.length;
            var datArr = [];
            for (var j = 0; j < ll; j++) {
                datArr.push(dat[j].attributes['value'].value);
            }
            data.push(datArr);
        }
    }
    // Now 'data' is the array

    // dataString is a JSON representation of the array to send to the server
    var dataString = JSON.stringify(data);

    // Test
    console.log(data);
    console.log(dataString);

    $.ajax({
        url: 'parse.php?submittedResults' + dataString,
        type: 'GET',
        dataType: "json",
        async: false
    }).done(function(data) {

    })
});

PHP：

if (isset($_GET['submittedResults'])) {
    if (empty($_GET['submittedResults'])) {
        die('Give me something to work with!!');
    }
    $resultSet = (string) $_GET['submittedResults'];
    $path = $resultSet;
    if (strpos($path, '../') !== false || strpos($path, "..\\") !== false || strpos($path, '/..') !== false || strpos($path, '\..') !== false) {
        http_response_code(403);
    } else {
        $getFile = file_get_contents('$path');
        $json_obj = json_decode($getFile);
        echo "$json_obj";
        $fp = fopen("clients/downloads/csv/$path.csv", 'w');
        foreach ($json_obj as $row) {
            fputcsv($fp, $row);
        }
        fclose($fp);
    }
}

JSON：

[["uploads/featured/doublewm-4097.jpg","featured"],["uploads/featured/moon-5469.jpg","featured"]]

所以我注意到我错过了'='符号...我重写了ajax调用以匹配你的建议，行为是一样的。我还包括下面要求的回声，结果如下：

请求的回音：

 var_dump($_GET['submittedResults'])

string(101) "[["uploads/featured/doublewm-3683.jpg","featured"],["uploads/featured/doublewm-3935.jpg","featured"]]"

PHP警告：file_get_contents（$ path）：无法打开流：没有这样的第62行/Users/Admin/Sites/dev/parse.php中的文件或目录

$resultSet = (string) $_GET['submittedResults'];
$path = $resultSet;

这会导致问题，因为$ path等于json数据。哪个错了，路径应该是文件名。试试这样：

//$resultSet =(string) $_GET['submittedResults'];
$resultSet = '[["uploads/featured/doublewm-4097.jpg","featured"],
           ["uploads/featured/moon-5469.jpg","featured"]]';
$path = "myfile.csv"; //or clients/downloads/csv/myfile.csv
if (strpos($path, '../') !== false || strpos($path, "..\\") !== false 
  || strpos($path, '/..') !== false || strpos($path, '\..') !== false) {
    http_response_code(403);
} else {
    $json_obj = json_decode($resultSet);
    echo "$json_obj";
    $fp = fopen($path, 'w');
    foreach ($json_obj as $row) {
        fputcsv($fp, $row);
    }
    fclose($fp);
}

myfile.csv：

uploads/featured/doublewm-4097.jpg,featured
uploads/featured/moon-5469.jpg,featured

编辑：提供唯一的文件名

$json_obj = json_decode($resultSet);
$path = $json_obj[0][1].".csv";

输出

featured.csv

将JSON数组从Javascript传递给PHP并转换为csv
